-# Contribution Guidelines
-
-Ensure your pull request adheres to the following guidelines:
-
-- Follow the format `- [Name](link) - A small description.`
-- Maintain alphabetical order in each category.
-- Submitted projects must meet a popularity threshold:
-    - **GitHub:** Minimum 50 stars.
-    - **Other Platforms:** Comparable community interest.
-
-I apologize if this feels like an arbitrary hurdle. Unfortunately, to keep this list focused and manageable, 
-and to ensure it highlights projects that have demonstrated some level of community validation, 
-I need a way to fairly filter submissions. I simply cannot include every project, and without some kind of metric, 
-reviewing and rejecting projects becomes very subjective and unsustainable.
-
-This check is an attempt to introduce a degree of fairness and objectivity to the process. Thank you for your understanding.
